“…Some studies reporting the Hg content of fungal sporocarps have included ectomycorrhizal species (Falandysz & Chwir 1997;Svoboda et al 2000;Vetter & Berta 2005). In an area in Poland remote from any point source of pollution, reported median Hg concentrations in tissue relative to that of the underlying soil (bioconcentration factors) in Amanita muscaria were 9 (cap) and 4.7 (stalk), and bioconcentration factors of Russula aeruginea (cap) were correlated to the Hg content of the soil (Falandysz & Chwir 1997).…”

“…Except for CK, the A. bisporus had lower Cd accumulation than the soil substrates, thus resulting in a relatively low BCF. The reason may be due to the short growing-time of the fruiting body 34 . However, A. bisporus can survive in high Cd content stress and accumulate high Cd content in a short lifetime, indicating its toleration potentialities in a Cd-contaminated soil environment.…”

The bioremediation of heavy metals contaminated soils with macrofungi is a new and promising approach; hence Agaricus bisporus (Large) sing has potentially shown accumulating ability to Cd contamination. This study focused on the tolerance response by A. bisporus to different contents of Cd in the closed cup and the flat stage of fruiting body development. The contents of Cd, soluble protein, sugar, low molecular weight organic acids (LMWOAs), and antioxidant activity were investigated. The bioaccumulation factor and transfer factor results revealed that Cd accumulated in the cap of A. bisporus more than that in the stipe with the highest content being 18.38 mg kg−1 dry weight at the closed cup stage under 414.28 mg kg−1 Cd stress. High Cd content stress increased soluble protein, proline, and malonaldehyde contents at both stages; while higher peroxidase, catalase, ascorbic acid peroxidase activities, and LMWOAs contents were only recorded at the closed cup stage. On the other hand, Superoxide dismutase activities and soluble sugar content showed a complex trend. Overall, these results have successfully established that A. bisporus could resort to modulating its metabolism to avoid the destructive effects of Cd stress and could successfully accumulate Cd in the soil, which is a promising prospect for the remediation of Cd-contaminated soils.

“…Soil properties were shown to significantly affect the transformation of As species. Mendil 284,285 used microwave digestion and AAS to determine trace metals including Cd and Pb in mushrooms collected in Turkey, while Vetter 286 used CVAAS to assess the Hg content of the mushroom Agaricus biporus, which showed it to be an order of magnitude lower than the reported values for wild mushrooms.…”
